Write the expression for the number of microbes in the sample

1) after day one

2) after day two

Use these expressions to help determine the number of microbes in the sample after the eighth day

Using only variables, "m", "n"" and "a", derive the general formula for the number of microbes found after "a" days.

**Reiny**, Monday, October 1, 2012 at 9:07pmNow we have M

after day 1 , we have Mn

after day 2 , we have Mn(n) = Mn^2

after day 3, we have (Mn^2)(n) = Mn^3

.

.

after day a, we have Mn^a

Number(a) = Mn^a

**Meagieting**, Tuesday, October 2, 2012 at 8:27pmI don't understand the symbol^.

For example for day 2..Is this the same as saying Mn to the 2nd power?

**Meagieting**, Tuesday, October 2, 2012 at 10:05pmOk so I figured out it's exponent...would it be correct to write The answers as follows?

M.n

M.n^2

M.n^8

M.n^a
